EchoConnect

The project will ultimately enable easy communication between computers that do not require any additional services (Bluetooth / WiFi), using high-frequency sounds. We will create a documented transmission protocol that supports error correction and transmission validation. On its basis, we are going to build a mechanism that allows you to transfer files or text between computers. The whole will be wrapped in API made available in the form of shared libraries (.so / .dll). In addition, we've created sample applications (CLI / QT) that use this API to present its capabilities.

Use cases:

• People with defective/poor computer set
• Hobbyists and curious people

Functionalities:

• Data transmission by sound
• Error correction, verification of correctness
• API
• CLI + GUI app using the API

Technologies used:

• Language: C++
• Audio support, GUI: QT
• Tests: GoogleTest
• Documentation: Doxygen
• Linter: clang-tidy
• Formatter: clang-format

Tools:

• Repository: Github
• Issue tracker: Github Issues
• Project management: Github Projets
• Continuous Integration: Github Actions
